I need to build some complicated queries for a TYPO3 extension. One of these queries is looking for a custom entry in the set of a given user or in the set of the default entries. The default entries are saved with cruser_id = 0. Therefor it's necessary to build nested logical operators.
I tried it as follows:
public function findById($cId, $userId) {
$query = $this->createQuery();
$query->getQuerySettings()->setEnableFieldsToBeIgnored(['pid', 'cruser_id', 'sys_language_uid']);
$res = $query->matching(
$query->logicalAnd(
$query->equals("id", $cId),
$query->logicalOr(
$query->equals("cruser_id", $userId), //include custom entries
$query->equals("cruser_id", 0) //also include default entries
)
))->execute()->getFirst();
print_r($res);
And that doesn't work :-( I tried to debug, but I found no indication for an error in my code. It would be great, if someone can help me here.
To sum up the comments:
If your records are located not in configured persistence-pid plugin.tx_yourext.persistence.storagePid, or you don't have a persistence storage configured at all, then you need to disable pid-checks.
setEnableFieldsToBeIgnored can apply only to so-called enable-fields, which in most cases are disabled, endtime, fe_group, starttime and configured via $GLOBALS['TCA'][$table]['ctrl']['enablecolumns'].
To suppress pid-check, you should use setRespectStoragePage(false). For sys_language there is a setRespectSysLanguage(false). And cruser_id is not checked at all, so you can skip it.

I'm new to CKAN and encountered a problem with template helpers. Particularly in my case, I will have to invoke toolkit.get_action('group_list') in my own template helper. However, when I add the constraint like the following:
results = toolkit.get_action('group_list')(data_dict={'sort': 'package_count desc',
'type': 'MyType',
'all_fields': True})
The results that I get back is an empty list. If I remove the 'sort' constraint from the data_dict, I can get the results of list the groups with 'MyType'. I don't know what caused this problem, because when I followed ckan toolkit official examples, it works for without any problems. However, what I can think of is this customized group might have its own schema such that package_count can not be used as a sort key. Since there's no error message, I can't make further assumption.
I figured out my own problem. The implementation I've showed in my question is correct. However, the database is not being populated properly. Basically you have to populate some packages for the particular groups. If you have no packages within each groups this function will return an empty query result. With the advice of #DRead, I researched the source code of _group_or_org_list(). If you take a look at this piece of code:
if sort_info and sort_info[0][0] == 'package_count':
query = model.Session.query(model.Group.id,
model.Group.name,
sqlalchemy.func.count(model.Group.id))
query = query.filter(model.Member.group_id == model.Group.id) \
.filter(model.Member.table_id == model.Package.id) \
.filter(model.Member.table_name == 'package') \
.filter(model.Package.state == 'active')
else:
query = model.Session.query(model.Group.id,
model.Group.name)
If you don't have packages created for groups, filter(model.Member.table_id == model.Package.id) will filter all groups out.
I have a problem with creating default value of 'All values' for a cascading parameter group last parameter. Actually I don't neccesary need that value to be default, but that would be preferable.
I have tried where I create additional data set with the needed value and additional data set with value All which uses different scripted data source, and another data set with computed column with full outer join, that column uses this code
if(row["userName"]==null ){
row["All"];
}else{
row["userName"];
}
and in the last cascaded parameter JDSuser which I need that All value I have added default value (All users).
In the data set with one value All in open I have script
ii=0;
in fetch
if( ii > 0 ){
return false;
}else{
row["All"] = "(All Users)";
ii++
return true;
}
and in the query data set, in beforeOpen script in if statement I have
if( params["JDSuser"].value!=null && params["JDSuser"].value[0] != "(All Users)" ){
This is used if I haven't selected All users value, and this works, though if I select All Users, it retrieves me no data.
I'm creating from this source example actuate link for example rptdesign download
If someone could give me some help, I would be very grateful.
The way you generate "(All values)" item in your selection list seems to me over complicated but if i understood correctly your case this part is working fine, the problem is not in the definition of the cascading parameter but the way it is used in the main dataset of the report.
Furthermore we have to assume we speak about the same query & beforeOpen script involved in this topic. No data are returned because if we don't do anything special when this item "All values" has been selected, then those filters are still active:
and role.name in ( 'sample grupa' )
and userbase.userName in ( 'sample' )
There are a couple of options to handle this. An elegant one is to declare a dataset parameter linked to your report parameter "JDSuser", and use a clause "OR" such:
and role.name in ( 'sample grupa' )
and (?='(All users)' OR userbase.userName in ( 'sample' ))
Notice this question mark, which represents a dataset parameter in your query. It is not intrusive: the beforeOpen script doesn't have to be changed. You probably need to do something similar with the other filter role.name, but you don't provide any information related to this. One more thing, in order to avoid bad surpises may be you should choose as value something more simple without brackets such "_allitems", and set "(All items)" as label.
Please refer to this topic for more informations about handling optional parameters. See a live example of optional parameters in a cascading group here.
During dehydration I create a custom value:
def dehydrate(self, bundle):
bundle.data['custom_field'] = ["add lots of stuff and return an int"]
return bundle
that I would like to filter on.
/?format=json&custom_field__gt=0...
however I get an error that the "[custom_field] field has no 'attribute' for searching with."
Maybe I'm misunderstanding custom filters, but in both build_filters and apply_filters I can't seem to get access to my custom field to filter on it. On the examples I've seen, it seems like I'd have to redo all the work done in dehydrate in build_filters, e.g.
for all the items:
item['custom_field'] = ["add lots of stuff and return an int"]
filter on item and add to pk_list
orm_filters["pk__in"] = [i.pk for i in pk_list]
which seems wrong, as I'm doing the work twice. What am I missing?
The problem is that dehydration is "per object" by design, while filters are per object_list. That's why you will have to filter it manually and redo work in dehydration.
You can imagine it like this:
# Whole table
[obj, obj1, obj2, obj3, obj4, obj5, obj5]
# filter operations
[...]
# After filtering
[obj1, obj3, obj6]
# Returning
[dehydrate(obj), dehydrate(obj3), dehydrate(obj5)]
In addition you can imagine if you fetch by filtering and you get let say 100 objects. It would be quite inefficient to trigger dehydrate on whole table for instance 100000 records.
And maybe creating new column in model could be candidate solution if you plan to use a lot of filters, ordering etc. I guess its kind of statistic information in this field so if not new column then maybe django aggregation could ease your pain a little.
I'm building a form with Yii that updates two models at once.
The form takes the inputs for each model as $modelA and $modelB and then handles them separately as described here http://www.yiiframework.com/wiki/19/how-to-use-a-single-form-to-collect-data-for-two-or-more-models/
This is all good. The difference I have to the example is that $modelA (documents) has to be saved and its ID retrieved and then $modelB has to be saved including the ID from $model A as they are related.
There's an additional twist that $modelB has a file which needs to be saved.
My action code is as follows:
if(isset($_POST['Documents'], $_POST['DocumentVersions']))
{
$modelA->attributes=$_POST['Documents'];
$modelB->attributes=$_POST['DocumentVersions'];
$valid=$modelA->validate();
$valid=$modelB->validate() && $valid;
if($valid)
{
$modelA->save(false); // don't validate as we validated above.
$newdoc = $modelA->primaryKey; // get the ID of the document just created
$modelB->document_id = $newdoc; // set the Document_id of the DocumentVersions to be $newdoc
// todo: set the filename to some long hash
$modelB->file=CUploadedFile::getInstance($modelB,'file');
// finish set filename
$modelB->save(false);
if($modelB->save()) {
$modelB->file->saveAs(Yii::getPathOfAlias('webroot').'/uploads/'.$modelB->file);
}
$this->redirect(array('projects/myprojects','id'=>$_POST['project_id']));
}
}
ELSE {
$this->render('create',array(
'modelA'=>$modelA,
'modelB'=>$modelB,
'parent'=>$id,
'userid'=>$userid,
'categories'=>$categoriesList
));
}
You can see that I push the new values for 'file' and 'document_id' into $modelB. What this all works no problem, but... each time I push one of these values into $modelB I seem to get an new instance of $modelA. So the net result, I get 3 new documents, and 1 new version. The new version is all linked up correctly, but the other two documents are just straight duplicates.
I've tested removing the $modelB update steps, and sure enough, for each one removed a copy of $modelA is removed (or at least the resulting database entry).
I've no idea how to prevent this.
UPDATE....
As I put in a comment below, further testing shows the number of instances of $modelA depends on how many times the form has been submitted. Even if other pages/views are accessed in the meantime, if the form is resubmitted within a short period of time, each time I get an extra entry in the database. If this was due to some form of persistence, then I'd expect to get an extra copy of the PREVIOUS model, not multiples of the current one. So I suspect something in the way its saving, like there is some counter that's incrementing, but I've no idea where to look for this, or how to zero it each time.
Some help would be much appreciated.
thanks

OK, I had Ajax validation set to true. This was calling the create action and inserting entries. I don't fully get this, or how I could use ajax validation if I really wanted to without this effect, but... at least the two model insert with relationship works.
Thanks for the comments.
cheers

I'm using Symfony 1.2 with Doctrine. I have a Place model with translations in two languages. This Place model has also a nested set behaviour.
I'm having problems now creating a new place that belongs to another node. I've tried two options but both of them fail:
1 option
$this->mergeForm(new PlaceTranslationForm($this->object->Translation[$lang->getCurrentCulture()]));
If I merge the form, what happens is that the value of the place_id field id an array. I suppose is because it is waiting a real object with an id. If I try to set place_id='' there is another error.
2 option
$this->mergeI18n(array($lang->getCurrentCulture()));
public function mergeI18n($cultures, $decorator = null)
{
if (!$this->isI18n())
{
throw new sfException(sprintf('The model "%s" is not internationalized.', $this->getModelName()));
}
$class = $this->getI18nFormClass();
foreach ($cultures as $culture)
{
$i18nObject = $this->object->Translation[$culture];
$i18n = new $class($i18nObject);
unset($i18n['id']);
$i18n->widgetSchema['lang'] = new sfWidgetFormInputHidden();
$this->mergeForm($i18n); // pass $culture too
}
}
Now the error is:
Couldn't hydrate. Found non-unique key mapping named 'lang'.
Looking at the sql, the id is not defined; so it can't be a duplicate record (I have a unique key (id, lang))
Any idea of what can be happening?
thanks!
It looks like the issues you are having are related to embedding forms within each other, which can be tricky. You will likely need to do things in the updateObject/bind methods of the parent form to get it to pass its values correctly to its child forms.
This article is worth a read:
http://www.blogs.uni-osnabrueck.de/rotapken/2009/03/13/symfony-merge-embedded-form/comment-page-1/
It gives some good info on how embedding (and mergeing) forms work. The technique the article uses will probably work for you, but I've not used I18n in sf before, so it may well be that there is a more elegant solution built in?
